I am interested in using your mica for the same thing. Specifically lip applications. I already know this much: Micas do not all contain the same ingredients so a test of one does not = all are good. For instance, mica that contains Carmine is safe for lips and eyes but not for soap making. Mica that contains Ferric Ferrocyanide is not safe for the lips or soap making but is okey dokey for the eyes. Do you or Can you list the ingredients in each of the colors that you carry? That would be really nice. I have a Mica Safety chart and that way I will know which are safe and which are not.
